Android billing 6 进入initiatePurchase 函数，之后不执行任何操作

Question

我是 Android 计费新手。我正在实施一项包含 4 种消费品购物选项的活动。所以我有 4 个按钮。当用户点击其中任何一个时，会出现 toast initiatedPurchase(productId: String) ，表明他们已进入该功能，但此后没有其他任何反应。知道可能出了什么问题吗？

private fun initiatePurchase(productId: String) {

        Toast.makeText(applicationContext, "initiatePurchase(productId: String)", Toast.LENGTH_SHORT).show()

        // Define the product details to query
        val productList =
            listOf(
                QueryProductDetailsParams.Product.newBuilder()
                    .setProductId(productId)
                    .setProductType(BillingClient.ProductType.SUBS)
                    .build()
            )

        // Create query parameters
        val params = QueryProductDetailsParams.newBuilder().setProductList(productList).build()

        // Query product details
        billingClient.queryProductDetailsAsync(params) { billingResult, productDetailsList ->
            if (billingResult.responseCode == BillingClient.BillingResponseCode.OK) {
                if (productDetailsList.size > 0) {
                    // Extract the product details
                    val productDetails = productDetailsList[0]

                    // Get the price of the product
                    val price = productDetails.getOneTimePurchaseOfferDetails()?.getFormattedPrice()

                    // Update the corresponding TextView with the price
                    when (productId) {
                        PRODUCT_ID_1 -> findViewById<TextView>(R.id.price1).text = price
                        PRODUCT_ID_2 -> findViewById<TextView>(R.id.price2).text = price
                        PRODUCT_ID_3 -> findViewById<TextView>(R.id.price3).text = price
                        PRODUCT_ID_4 -> findViewById<TextView>(R.id.price4).text = price
                    }

                    // Create BillingFlowParams using the product details
                    val productDetailsParamsList =
                        listOf(
                            BillingFlowParams.ProductDetailsParams.newBuilder()
                                .setProductDetails(productDetails)
                                .build()
                        )

                    val billingFlowParams =
                        BillingFlowParams.newBuilder()
                            .setProductDetailsParamsList(productDetailsParamsList)
                            .build()

                    // Launch the billing flow
                    billingClient.launchBillingFlow(this@Purchase, billingFlowParams)
                } else {
                    Toast.makeText(applicationContext, "Not found", Toast.LENGTH_SHORT).show()
                }
            } else {
                Toast.makeText(applicationContext, "Error " + billingResult.debugMessage, Toast.LENGTH_SHORT).show()
            }
        }
    }

谢谢。

计费流程参数需要设置

setOfferToken

。 类似于下面，

BillingFlowParams.ProductDetailsParams.newBuilder()
                                         .setProductDetails(productDetails)
                                         .setOfferToken(offerToken)
                                         .build()

您可以提供以下代币

productDetails.getSubscriptionOfferDetails().get(0).getOfferToken()
